Claims

[Scope of utility model registration request]

The vicinity of the joint surfaces of the reinforcing bars to be connected held by the fixed gripping part and the movable gripping part of the reinforcing bar clamping device is heated, and the movable gripping side is moved under pressure by a hydraulic ram, and the joint is performed while detecting the displacement of the joint part. In a gas pressure welding device, a hydraulic pump, hydraulic related equipment, and a pressure transmitter are combined into a unit, and the output side of the pressure transmitter, which is divided into two chambers, is connected to the hydraulic ram via a piston within the unit. Connect with a hose, fill with pressurizing oil, and connect the input side of the pressure transmitter with oil.
1. A compression displacement detection device for a joint in gas pressure welding work, characterized in that it is connected to a pressure pump, a displacement detection rod is directly connected to the piston of the pressure transmitter, and the end of the rod is associated with a detection mechanism.
